Dynamic Blast Load Experiment

• The slabs reinforced with vanadium micro-alloyed
  rebar and high strength concrete resulted in 20
  less deflection and 25 less rotation than slabs
  reinforced with Grade 60 rebar and high strength
  when loaded with similar pressures and impulses.
• A reduction of 45 less deflection and 84 less
  support rotation was observed in the vanadium
  micro-alloyed rebar and conventional concrete
  reinforced slabs, in comparison to the Grade 60
  rebar and conventional concrete reinforced slabs.
• The increased protection provided by using
  vanadium micro-alloyed rebar was witnessed in the
  dynamic blast load tests. The type of concrete
  used in construction will determine the level of
  protection provided. High strength concrete with
  vanadium micro-alloyed rebar provided the best
  results in terms of the least amount of damage
  and survival of the greatest loading in this test
  series.
